Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed April 8, I904. Serial No. 202,202.

To all whom it may concern:

Be it known that I, ARTHUR W. TOWER, a citizen of the United States, and a resident of Rockland, in the Commonwealth of Massachusetts, have invented an Improvement in Blacking Attachments for Vamp-Skivers and the Like, of which the following description, in connection with the accompanying drawin s, is a specification.

efore vamps are assembled and stitched to the rest of the shoe it is necessary to skive the edges of the upperfor instance, where it is to be stitched to the topand the same remark applies to the edges of the backstay, tongue, tip, &c., and the edge of the material is thereafter brushed over with ink by hand, and as handwork is necessarily more-or less uncertain. the result is that the adjacent portions are frequently blacked and discolored, being sometimes entirely spoiled, especially when the leather is delicate or the adjacent parts are of a different color.

The object of my present invention is to provide means for accomplishing automatically in a neat and compact manner all that has heretofore been done by hand, and I have shown my invention applied for convenience to an Amazeene skiverin such manner that the blacking is done with extreme neatness and is confined absolutely to the raw edge' which it is desired to color.

The constructional details of my invention will be pointed out and fully described in the course of the following description, reference bein had to the accompanying drawings, in which I have illustrated one of the preferred embodiments of my invention, the latter be-' ing more particularly defined in the appended claims, also forming a part of this specification.

In the drawings, Figure 1 represents in side elevation suflicient parts of a skiving machine to make the application of my invention thereto readily understood. Fig. 2 is a top plan view of the guide-plate of the machine containing my improvement, parts being broken away and sectioned for clearness of illustration. Fig. 3 is a longitudinal sectional view thereof. Fig. 4 is an enlarged fragmentary view in longitudinal section. Fig. 5 is a perspective view of the brushholder and ink-conveyer. Fig. 6 is a view in end elevation looking at the machine from the left, Fig. 1. Fig. 7 is a top plan view of a modified form of attachment. Fig. 8 is a central horizontal sectional view of the attachment shown in Fig. 7.

It will be understood that my invention is not limited to any particular skiving-machine, although I prefer to use it in connection with the Amazeene skiver which is commonly employed for skiving the edges of the uppers, backstays, tongues, tips, (520., the leather being fed to a rotary cutter a by a feed-roll a, against which it is held by a rotary presser-wheel a and passes beneath a yielding holder or projection 6, whose beveled edge 6 serves to hold the extreme edge of the leather down tightly upon the feed-roll a, said edge .of the leather resting against a curved guide 6 projecting from the guideholder or gage device 6 In this ga 'e device b I provide a cavity 6 shown as enlarged at its outer end to provide a flattened pocket b corresponding in shape to the brush which is subsequently inserted. Within this cavity I mount a shell I), in whose outer end is a brush 6 adapted to be supplied with ink through the tubular opening b of the shell I). This shell extends back to an ink pot or can 0, be-,

ing shown in Figs. 2 and 3 as passing therethrough, and provided in its upper side with an opening 0 to admit the ink from said pot.

An important feature of my invention resides in providing proper means for controlling the ink-delivery to the brush, this problem being diflicult because of the fact that this ink is extremely fluid, being composed largely of ether, and hence an ordinary regulating.- valve will not control it, and also as the ink is used very slowly and as there are long periods when it is not used the controlling device must be of a nature to prevent the tendency of the ink to clog by the evaporation of the ether. I have found that by providing means for delivering the ink to the body of the brush-as, for instance, by having a hollow nipple b, around which the brush is secured, as clearly shown in Fig. 4, and by having a delicate needle-valve I), carried by a rod 1) for controlling the flow of ink to this nipp1eproper results are secured. The rod 6 extends centrally the length of the shell I) and is operated by a thumb-nut I2 The position'of the shell'is regulated by a thumb-nut b and a slide-rod I), engaging a clamp 6 at its inner end secured to the gage b thereby enabling the brush to be projected more or less as desired.

In Figs. 7 and 8 I have shown a modified iorm of regulation and general construction, the gage b being provided with a second passage dd, offset at dflwhere a needle-valve d is located and o erated by a stem d, the brush 1) being arfjusted in and out by a rod b In this construction the offset between the two ducts d d renders it easy to clean the valve-seat and to remove the needle-valve and also brings the latter into very convenient position for careful regulation by the operator as he stands in front of the machine.

The operation of my invention will readily be understood. The work is fed through the machine by the feed-wheel a and the presserwheel a guided by the guide I) and held down at b, and as the white or red edge of the raw-cut leather passes in front of the brush 6 it is neatly and evenly blacked, said blacking being confined entirely to said edge, so that it cannot possibly become applied to the dressed outer surface of the leather. This blacking takes place as rapidly as the leather is fed through the machine and requires no attention whatever from the operator, who simply feeds the leather through the skivingmachine with the same rapidity and devoting his entire attention to the skiver, as be fore.

When the machine is at rest, the needleval-ve may be closed, and the feed of the ink is at all times regulated with the utmost nicety by said needle-valve. By the terms ink and blacking I do not intend to confine myself to any particular color or substance.

In practice the shell or .casing b may be made in detachableportions, as indicated at I), and may have a vent b for ether to start the ink if clogged, and various constructional details may be modified and equivalent constructions substituted without departing from the spirit and scope of my invention, and accordingly I wish it understood that I do not'limit my invention otherwise than as stated in the claims, taken in connection with the rest of this specification.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A skiving-machine, comprising feeding mechanism, a skiving-cutter for beveling to a thin edge the leather operated upon, means for guiding said beveled edge, and means located adjacent said skiving-cutter and cooperating with said guiding means and feeding mechanism for automatically blacking the extreme edge of the leather as it is fed through the machine, said blacking means being directed solely to the said extreme edge and having means restricting the application of the blacking to the transverse edge beyond the skived surface of the leather.

2. A skiving-machine, comprising a skiving-cutter, an edge-guide, feeding mechanism cooperating with said cutter and guide for passing the thin, raw edge of the leather through the machine, holding means adjacent said cutter for pressing the leather down upon said feeding mechanism and maintaining said thin edge flat and straight, and means located in the path of the edgeguide between said feeding mechanism and holding means for automatically .blacking the extreme, raw edge of the leather as it is fed along, said blacking means being so located and constructed as to maintain the skived surface of the leather untouched with the blacking and restrict the latter solely to the raw, transverse portion of the thin .edge pt the extremity of the skived or beveled surace.

3. A skiving-machine, comprising a skivingmutter, edge-guiding mechanism, feeding mechanism adjacent thereto, and means cooperating with said edge-guiding mechanism and feeding mechanism for holding the extreme edge of the leather down flat on said feeding mechanism and against said edgeguiding mechanism, and a brush having its operative surface restricted to a portion of the edge-guiding surface immediately adjacent said holding means, and a needle-valve for regulating the flow of ink to said brush,

4. A skiving-machine, comprising a skiving-cutter, feeding mechanism having its feeding surface approximately parallel to said skiving-cutter for holding the leather in proper position to be skived to a thin edge, an edge-guide above said feeding mechanism and in front of said skiving-cutter for supporting said thin edge, means cooperating therewith for holding said thin edge down against said edge-guide, means containing a recess extending back from said edge-guide, a brush mounted in said recess, having its free end terminating substantially in the guiding-surface of said edge-guide, and an ink duct for supplying ink to said brush.

5, A skiving-machine, comprising a skiving-cutter, feeding mechanism having its feeding-surface approximately parallel to said skiving-cutter for holding the leather in proper position to be skived to a thin edge,

an edge-guide above said feeding mechanism and in front of said skivingscutter for supporting said thin edge, means cooperating therewith for holding said thin edge down straight against said edge-guide, means containing a recess extending back from said edge-guide, and a brush in said recess extending back in a direction approximately parallel to said feeding mechanism, a hollow nipple extending longitudinally into the rear end of said brush, a duct for directing ink to said nipple, and a valve for controlling the ink-delivery thereto.

6. A skiving-machine, comprising feeding mechanism, skiving mechanism, a gage having a guiding-surface against which the eX- treme edge of the piece of leather being skived rests, a passage-way in said gage, and a removable case held in said passage-way provided at its end adjacent said surface with a brush-holder containing a brush, and having an ink-duct for delivering ink to said brush.

7. In a skiving-machine, a gage extending in a plane approximately parallel to the plane of the leather being gaged thereby and having a surface for receiving and guiding the extreme edge of the leather being skived, said gage having a longitudinal recess, containing a removable case provided at one end with a brush-holding portion containing a nipple for entering within the brush and delivering ink inside of the latter, said brushholding portion of said case being removable from the rest of the case, and a brush in said brush-holding portion of the recess.

8. A skiving-machine, comprising feeding mechanism, cutting mechanism, a gage having a guiding-surface against which the raw edge of the material being skived rests, a brush in said gage having its operative end extending flush with said surface, an ink-can, and means connecting said can and brush for adjusting the same with relation to said gage.

In Witness whereof I have signed my name to this specification in the presence of two subscribing witnesses.
